摘　　要：The effect of HF treatment on etherification activities of ZSM-5 zeolite was investigated.Appearance,crystal structure,pore structure,acid quality of treated zeolite was charactered.It was found that catalyst treated by HF remained typical MFI structure,but grain broken;pore volume and average pore diameter of treated zeolite increased obviously;Brnsted acid quantity decreased;etherification activities of fluorinate treatment of ZSM-5 zeolite increased obviously.The effect of HF treatment on etherification activities of ZSM-5 zeolite was investigated.
